via api created only first particpant gets a line: "Contribution Amount: 1"

Question

I register participants and payments via the API. Step 1: create a contribution for the buyer Step 2: create participants Step 3 create participant_payments linking the above.

The weird thing is that civi adds a line to the fee_level of the first participant stating "Contribution Amount: 1".

Why? Am I doing something wrong?

Following the suggestion of Jon G I have been able to pin this down to something related to price sets. Participants of events that do not use price sets do not get this "contribution amount: 1"-line.

Kind regards,

The api calls:

1) create participant:

public function createParticipant($civiEventId, $contactId, $customFields = [], $amount, $currency, $fee_level) {
$entity = 'Participant';
// Create filter.
$params = [
  'event_id' => $civiEventId,
  'contact_id' => $contactId,
  'status_id' => "Registered",
  'participant_role_id' => "deelnemer",
  'participant_fee_level' => $fee_level,
  'participant_fee_amount' => $amount,
  'participant_fee_currency' => $currency
];
if (count($customFields) > 0 && is_array($customFields)) {
  foreach ($customFields as $customFieldKey => $customFieldValue) {
    if(is_integer($customFieldKey)){
      $customId = "custom_".$customFieldKey;
    } else {
      $customId = $customFieldKey;
    }
    $params[$customId] = $customFieldValue;
  }
}
$action = "create";

return $this->query($entity, $params, $action);

}

2) create contribution

public function createContribution($financial_type, $total_amount, $civi_id, $mollie_id, $date) {
$entity = 'Contribution';
$action = 'create';
// Create filter.
$params = [
  'financial_type_id' => $financial_type,
  'total_amount' => $total_amount,
  'contact_id' => $civi_id,
  'custom_100' => $mollie_id,
  'receive_date' => $date,
  'currency' => "EUR",
  'source' => "Chiro.be via mollie",
];
return $this->query($entity, $params, $action);

}

3) create participantPayment

public function createParticipantPayment($participant_id, $contribution_id) {
$entity = 'ParticipantPayment';
$action = 'create';
// Create filter.
$params = [
  'participant_id' => $participant_id,
  'contribution_id' => $contribution_id,
];
return $this->query($entity, $params, $action);

}

using version 4.7.27.

Answer 1

This is not a right way of adding participant with contribution associated with it. When there is payment associated with Participants than we need to specify line items in create Participant and/or Contribution api. I would suggest to use Order api to achieve your needs as it is straight forward and handles in convenient way for adding payments in CiviCRM.
